by the FCC.
Hearing-Aid Compatibility (HAC) Features
of this Phone
This Virgin Mobile phone has been certified as
receiving an M4 rating for hearing aid-compatibility
performance. While there is no guarantee, digital
wireless phones that receive a minimum of an M3
rating should provide acceptable performance with
most hearing aids. Hearing loss and hearing aids are
highly individualized, however, so optimal
performance cannot be guaranteed. Other factors,
such as type of hearing aid device or degree of
hearing loss, also can affect a phone's performance
for a particular user.
Hearing Aids and Wireless Phones
A hearing aid uses a microphone to collect
and convert sound waves to electrical signals.
The hearing aid then amplifies and converts the
electrical signals back to audible sounds for the
hearing aid user to hear. Radiofrequency (RF)
emissions generated by digital wireless phones often
interfere with the operation of a hearing aid's
microphone, distorting the amplified audible sound.
In addition, hearing aid microphones tend to collect
ambient noise and amplify these sounds, interfering
with the desired audio transmission.
ANSI Standard
To diminish interference between wireless phones
and hearing aids, the FCC requires wireless carriers
to offer phones that meet the American National
Standards Institute (ANSI) C63.19 standard for
reduced RF emissions. Wireless phones that comply
with the FCC's hearing aid-compatibility (HAC)
User Guide for the MARBL Phone
regulations must receive a minimum rating of "M3" for
RF emissions under the ANSI C63.19 standard. The
"M" rating refers to the phone's RF emissions level for
use with hearing aids operating in the microphone
setting. The higher the phone's "M" rating, the more
likely the phone is compatible with a hearing aid
operating in the microphone setting. Hearing aids
also have ratings similar to wireless phones.
Most newer hearing aid models receive at least
an M2 rating.
To determine the level of compatibility between your
hearing aid and this Virgin Mobile HAC-certified
phone, combine the M rating of your hearing aid and
the M4 rating of this phone. For example, if you pair
an M3 hearing aid with this M4 phone, you will
achieve a combined rating of 7.
• Any combined rating equal to or greater than 6
provides excellent performance.
• Any combined rating equal to 5 offers
good performance.
• Any combined rating equal to 4 offers
acceptable performance.
T-Ratings— Phones rated T3 or T4 meet FCC
requirements and are likely to be more usable with a
hearing device's telecoil ("T Switch" or "Telephone
Switch") than unrated phones. T4 is the better/higher
of the two ratings. (Note that not all hearing devices
have telecoils in them.)
Hearing devices may also be measured for immunity
to this type of interference. Your hearing device
manufacturer or hearing health professional may help
you choose the proper rating for your mobile phone.
The more immune your hearing aid is, the less likely
you are to experience interference noise from mobile
phones.
